To aZZ whom it 'may concern:

Be it known that I, EDWARD J. HAYES, a citizen of the United States, residing at Marion, in the county of Grant and State of Indiana, have invented certain new and useful Improvements in Glass-Presses, of which the following is a specification.

This invention relates to the art of manufacturing pressed glassware, such as liners for the metal caps of fruit-jars, nappies, and other articles of glassware usually manufactured by means of a press embodying a mold and a plunger cooperating therewith.

To this end the invention contemplates certain novel and practical improvements in a glass-press of the type heretofore usually operated manually, whereby said press is converted into strictly a power-machine embodying means for facilitating and accelerating the manufacture of the glass articles.

A special feature of the invention is the provision of improved operating mechanism for the molds and plunger which permits the expansion of the glass in the molds in order that the article may be made of full weight; and another practical improvement resides in the provision of a mold-alining device which insures the checking of the momentum of the traveling mold and arresting the latter in accurate alinement under the plunger as the latter descends to press the glass.

With these and other objects in view the invention consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

The essential features of the invention involved in carrying out the objects above indicated are necessarily susceptible to structural modification without departing from the scope of the invention; but a preferred embodiment of the latter is shown in the accompanying drawings, in which Figure 1 is a front perspective View of a glass-press embodying the present invention. Fig. 2 is a perspective view of the press from one side thereof. Fig. 3 is a perspective view of the press viewed from the side opposite to that shown in Fig. 2. Fig. 4 is a detailed top plan view of the molding-table portion of the press, illustrating the relation of the traveling molds to the mold alining or stop device. Fig. 5 is a detail sectional view on the line 5 5 of Fig. 4. Fig. 6 is a detail in alining device.

In carrying out the present invention some features of the ordinary glass-press are preserved, as the improvements claimed herein relate particularly tov the power-operating mechanism and its various accessories and to the mold-alining device. However, the preferable complete embodiment of the invention is shown in the drawings, in which the numeral 1 designates the machine-supporting stand, having a horizontal top portion 2, within which is arranged a horizontal molding-table 3. Over this table is arranged to operate an endless mold-carrier essentially consisting ofan endless belt of mold-cups 6 arranged to travel above and below the table 3 and connected to and carried with a pair of opposite parallel carrier-chains 5. Hence the endless or traveling mold-carrier consists of the opposite carrier or sprocket chains 5 and a plurality of the open mold-cups 6, .arrange(: in regularly-spaced relation and swung between the chains. As the carrier is moved the molds are carried in upright position over guiding sprocket-wheels 7, arranged in pairs at opposite ends of the top portion 2 of the machine-stand and mounted on the oppositely-located carrier-shafts 8 and 9, respectively. The location of these shafts beyond the ends of the molding-table causes the separate horizontal runs of the carrier to travel, respectively, above .and below the moldingtable, while at the same time the molds reach and assume a discharging position as they pass over one of the carrier-shafts, in which discharging position (see Fig. 1) the glass is turned out of the mold-cup and falls into a receptacle in the usual way.

To provide for the proper intermittent feed of the endlesstraveling mold-carrier 4 5, there is associated with the same the improved power-operating mechanism claimed herein. This mechanism includes a driven pinion 10, mounted on one end of the carriershaft 8 and meshing with a ratchet spur-gear ratchet-arm 14, loosely swung at one end from the axis or journal support 12 of the spur-gear 11. The said swinging ratchetarm 14 has suitably connected therewith, as at 15, a reciprocating crank-rod 16, whose opposite end has a wrist-pin connection 17 with a driving crank-wheel 18. This crankwheel is mounted on one end of a drive-shaft l9, journaled in suitable bearings 20, fitted to one end of the machine-supporting stand,

and the end portion of the said shaft opposite the wheel 18 has mounted thereon a belt wheel or pulley 21, which receives the driving-belt from any suitable power-motor either of the electrical, steam, or gas type.

Cooperating with the mold-cups 4 as they are worked over the molding-table 3 is a reciprocating pressing-plunger 22. This plunger is associated with the ordinary guardcover 23, common to this type of glass-press, and said parts are arranged for support and operation within the usual upright guideframe 24, surmounting the top portion 2 of the machine stand and overhanging the molding-table. The relation and action of the plunger 22 and the guard-cover 23 are well understood by those familiar with the art; but to illustrate the application of the improved operating mechanism to the plunger device it is to be observed that the plunger 22 has associated therewith the plungeroperating cross-head 25, reciprocally arranged within the guide-frame 24 and having connected therewith the pivotal links 26. The links 26 are also pivotally connected to the rock-arms 27, carried by a rocker-shaft 28, journaled in bearings 29 provided on one side of the standards of the guide-frame 24. The shaft 28 is horizontally arranged and has fitted to one end thereof an overbalance operating-lever 30, carrying at one side of its axis a weight element 31 and having connected to its other end a compensating pitman 32. The other end of this pitman is pivotally connected by the wrist-pin connection 17 to the crank-wheel 18.

The compensating pitman by reason of its special arrangement and connections is a practical feature of the operating mechanism, inasmuch as it permits the expansion of the glass in the mold when the plunger enters the same, thereby causing the article to be made of the full weight of so much of the glass as the gatherer may have placed in the mold. The said compensating pitman 32 essentially consists of a yoke member 33 and a sliding rod member 34. The rod member 34 slides through a guide-strap 35 at one end of the yoke 33, and'the end of the rod within the yoke is adjustably connected, as at 36, with a cross-head 37 sliding upon the sides of the yoke. A pressure draw-spring 38is coiled on the rod member 34 and is interposed between the sliding cross-head 37 and the guidestrap 35.

The alining device for the molds embodies in its construction what maybe properly termed a verticallyswinging stop member 39. This stop member essentially consists of a carrying-rod 40, supporting at one end a cross-arm 41, carrying at its extremities upstanding stop-pins 42, adapted to be projected through pin-openings 43 in the molding-table 3, as plainly shown in Figs. 4 and 5 of the drawings. The end of the rod 40 opposite the pins is fitted to a transverse rock-shaft 44, journaled in suitable bearings at one end of the machine-stand and carrying at one end upon the outside of the frame a collar element 45. This collar element has endent therefrom an operatingrod 46 ,the ower free end of which is arranged at one side of an actuating-cam 47 on the drive-shaft 19. The said collar element 45 also has extended therefrom at an angle to the rod 46 an auxiliary operating-arm 48, beneath which is arranged an actuatingspring 49, exerting a pressure in a direction for oscillating the shaft 44 in.a contrary direction to that caused by the throw of the cam 47 against the rod 46.

It will be observed that the construction described provides means whereby the stoppins 42 Wlll be projected into the ath of a mold as it ap roaches a correctIyalined position beneat the plunger, so that by the time the plunger starts into the mold the latter has been checked and held in the proper position of alinement so that a perfect pressing operation may be carried out.
